Effects of area on breeding bird communities in urban forests in Daejeon Metropolitan, South Korea

초록

This study was conducted to clarify the effect of area on breeding bird communities in 35 urban forest fragments ranging from 2.1-1936 ha in Daejeon Metropolitan, South Korea. Bird communities were surveyed using the line transect method. Thirty seven species were observed and the number of resident species was higher than the number of visiting species. Hole and bush nesting guild species and bush and air foraging guild species were the most common. As the forest area increased, the number of bird species and bird species diversity index (H') increased significantly. The number of long-tailed tits (Aegithalos caudatus), Indian cuckoos (Cuculus micropterus), black-naped orioles (Oriolus chinensis) and yellow-throated buntings (.Emberiza elegans) were significantly related with forest area. Forest size may be a critical factor affecting bird communities in urban areas. For the conservation and management of avian species in urban areas, forest fragment size andstructural diversity of habitat should be maintained. © Medwell Journals, 2014.
